Reaction Steps

A 10 mL microwave vial was charged with 8-Chloro-2-[5-methyl-2-(2,2,2-trifluoro-ethyl)-2H-[1,2,4]triazol-3-yl]-4,5-dihydro-6-oxa-1,3a,9-triaza-benzo[e]azulene (85 mg, 0.22 mmol) and 2-(2-Methyl-benzyl)-pyrrolidine (231 mg, 6 eq). 0.5 mL of NMP and 0.5 mL of triethylamine was added. The vial was sealed and heated at 160° C. for 24 h. After cooling to room temperature, the solution was purified directly by reverse phase HPLC (0.1% NH4OH/ACN). The isolated solid was further purified by chiral SFC (AD column, 35% MeOH isocratic) to give 27 mg of one enantiomer and 29 mg of 420 (48% total yield). LCMS: 524.2. 1H NMR (400 MHz, DMSO) δ 9.08 (s, 1H), 9.08 (s, 1H), 7.92 (s, 1H), 7.27-7.06 (m, 4H), 5.99 (s, 1H), 5.80 (q, J=8.9 Hz, 2H), 4.50 (m, 4H), 4.38 (br s, 1H), 3.49 (t, J=8.6 Hz, 1H), 3.15 (d, J=10.0 Hz, 1H), 2.60-2.53 (m, 1H), 2.42 (s, 3H), 2.28 (s, 3H), 2.10-1.89 (m, 2H), 1.81-1.71 (m, 2H)
